What it is

Singapore Oceanarium is the Asia-Pacific's largest oceanarium, opened in July 2025 as the greatly expanded successor to the former S.E.A. Aquarium at Resorts World Sentosa. Three times larger than its predecessor, the attraction spans 22 immersive zones across six thematic chapters — from prehistoric marine life and one of the world's largest jellyfish kreisel habitats to the iconic 36-metre Open Ocean viewing panel housing manta rays, sharks, and tens of thousands of schooling fish. Admission also covers the adjacent Research and Learning Centre, daily animal programmes, and interactive touch pools, making it Singapore's most ambitious marine attraction to date.

Highlights

Open Ocean habitat: an 18-million-litre tank viewed through a 36 m × 8.3 m acrylic panel — one of the largest underwater viewing windows in the world — with reef manta rays, spotted eagle rays, and zebra sharks
Ocean Wonders: one of the world's largest kreisel habitats, housing thousands of in-house-bred moon jellies in a 6.8 m circular tank
22 immersive zones across 6 thematic chapters covering prehistoric seas, coastal ecosystems, deep-sea trenches, and ocean conservation futures
Whale Fall & Seamount: walk through a near-life-size whale skeleton with deep-sea species including Australian ghostsharks and hydrothermal vent simulations
Research and Learning Centre (adjacent, solar-powered Green Mark Platinum Zero Energy building): interactive marine labs, seminar rooms, and conservation programme spaces open to the public
Daily included animal programmes: Sea Jelly Secrets, Curious about Corals, Sensational Sharks, and Open Ocean Discovery Presentations at scheduled times

Frequently asked

What is included in a standard Singapore Oceanarium ticket?: A standard admission ticket covers all 22 zones across the six thematic chapters, access to the Pier Adventure suspended walkway, and all daily scheduled animal programmes (Sea Jelly Secrets, Curious about Corals, Sensational Sharks, and Open Ocean Discovery Presentations).

How long does a visit to Singapore Oceanarium take?: Most visitors spend 2–3 hours on a standard walkthrough.

There is no time limit on admission tickets.
Is Singapore Oceanarium the same as the old S.E.A. Aquarium?: Singapore Oceanarium opened in July 2025 as the successor to the S.E.A. Aquarium, which closed permanently on 30 April 2025.
